Is your feature request related to a problem? Please describe.

The project currently doesn't require more space than provided 4MB, however with new audio file storage features it might be useful for some users to have ability to extend flash size to 16MB.

That would require to desolder the flash chip and replace it with a bigger one.

Once we establish it works, I could enable new build process for the 16MB chip. There would be no overhead from the development perspective to support 2 chip versions.

Describe the solution you'd like

Also it seems that ESP32 can run SD cards directly so it might be an option to add a SD card reader on the bottom side of the ESPRI board.

V2 board support uSD cards and is a more elegant solution.
